Clinical Trial Summary

The purpose of this study is to identify radiological factors on TC of the hip that could lead to prediction of development of symptomatic psoas impingement in patients with protruding acetabular cup after primary total hip arthroplasty.

Eligibility

Inclusion Criteria:

• Primary total hip arthroplasty

• Execution of a postoperative Ct scan for pain, noises or planning of the contralateral THA

• 5 years minimum follow-up for the control group, tenotomy of the iliopsoas muscle in the cases group

• Complete clinical and radiological data

Exclusion Criteria:

• Patient's refusal to participate

• Non adequate Ct scans or made for periprosthetic fractures, component mobilization, periprosthetic infection or wearing of the prosthesis

• Incomplete clinical and radiological data

• Inadequate follow-up or regression of the iliopsoas impingement symptoms with non-operative treatment

Related Conditions & MeSH terms

• Hip Impingement Syndrome

Intervention

Diagnostic Test:
• Pelvis CT scan
Post-THA hip pelvis CT scan execution for pain, noise or THA planning for the controlateral hip, with identification of acetabular cup protrusion. Comparation of cases and controls to identify radiological factors that could potentially lead to symptomatic psoas impingement prediction.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Acetabular cup antiversion	The angle between the tangent to the cup opening and the tangent to the posterior ischial spines in the axial plane	0
Primary	Acetabular cup inclination	The angle between the tangent to the cup opening and the interteardrop line in the frontal plane	at baseline (day 0)
Primary	Femoral offset	The distance between the center of rotation and the femoral axis in the frontal plane	at baseline (day 0)
Primary	Acetabular offset	The distance between the center of rotation and the Kohler line in the frontal plane	at baseline (day 0)
Primary	Eccentric Reaming	The distance between the native hip center of rotation and the acetabular cup center of rotation in the axial plane	at baseline (day 0)
